In the mol-ecule of the title compound, C7H9N5O·0.40H2O, the seven-membered heterocyclic ring exhibits a boat conformation, whereas the five-membered triazole ring is almost planar (r.m.s. deviation = 0.005 Å). In the crystal, centrosymmetric dimers are linked by pairs of C-H⋯O hydrogen bonds into dimers, which are further connected via O-H⋯N and C-H⋯N hydrogen bonds, forming a three-dimensional network. The structure contains a partially occupied water mol-ecule lying on a twofold axis with an occupancy factor of 0.4.
在标题化合物C₇H₉N₅O·0.40H₂O的分子中，七元杂环呈船式构象，而五元三唑环几乎是平面的（均方根偏差 = 0.005 Å）。在晶体中，中心对称的二聚体通过成对的C—H⋯O氢键连接成二聚体，这些二聚体再通过O—H⋯N和C—H⋯N氢键进一步连接，形成三维网络。该结构包含一个位于二重轴上的部分占据的水分子，占据因子为0.4。
